Because the people who want their names chiseled in above the doors suffer from the same problem that Imus does. The ones who give quietly and anonymously, by definition, you don't hear about.
Imus himself today admitted as much that the donators who gave big money to get their names up on his ranch did so because they thought it was effective cheap advertising.
It would be nice if every charitable donation was done so with a free heart, unconditionally, no strings or egos attached, but most of the money donated doesn't come that way.
As I said in the beginning, I'm not a fan of his, but I do take exception to some of the comments made about his childrens' ranch, just because his ego is stroked by it.
Who cares? Well, apparently, you do.
The psychological reasons behind why people may set up a charitable venture, don't really matter much to me.
But ego-stroking motives don't make the charity any less a charity.
I don't know why you continue to listen to his show if you dislike him so much?
